\ This invention relates to screened windows that are adapted for use in various structures a window pane in different positions, and. V quick-actlon means of simple character for moving and ad ust1ng the window pane.

Another object is to provide improved window screen mounting and means for locking the screen in effective position.

-A further object is to provide improved means for controlling automobile window frames so that a heavy glass pane may be eflectually balanced in a simple manner and also held in adjusted position.-

A still further-"object is to provide an improved window pane and screen assembly of simple construction and also inexpensive controlling means therefor, and which shall beadapted to be readily installed in an automobile body factory. Y

With the above-mentioned and other objects in view, the invention consists in an improved automobile door and improved means for controlling a window pane therein, the invention consisting also further in the parts and combinations and arrangements of parts as hereinafter particularly described and defined in the appended claims.

Referring to the drawings,-Figure 1 is an elevation showing the outer side of a door structure suitable for a' closed-topautomobile to which theinvention is applied, the usual covering of the door being omitted; Fig. 2 is avertical transverse section approximately central of Fig. 1 on an enlarged scale and partially broken away; Fig. 3 is a horizontal sectionapproximately on the line III-III in Fig. 1, but including the usual covering panels to constitute a casing for the window pane and screen when lowered, together with means of controlling the window pane; Fig. 4 is an elevation showing the inner side of the door frame without the covering panels and showing the window pane and its controlling apparatus in different positions; Fig. 5 is m a fragmentary elevation of the outer side of the door and modified controlling means for the window pane; Fig. 6 is a fragmentary vertical transverse section in which the controlling means appears, on an enlarged scale; Fig-7 is a detail or balancing means for the window panes, on an enlarged scale; and Fig. 8 is'a fragmentary detail showing the modified means an on enlarged scale for holding the window. pane in adjusted position.

Similar reference characters in the various figures of the drawings indicate corresponding elements or features of construction herein referred to in detail.

The drawings. show a main frame which may be variously constructed as a window frame for various structures or as a door frame suitable for closed top automobiles and comprises a bottom. rail 1, posts 2 and 3 and a top rail a suitably connected together to constitute a rectangular frame which has intermediate rails 5 and 6 connected to the posts to constitute window sill members. For the purposes of the invention a cross-bar 7 preferably is provided and secured to the posts on a suitable lever below the window sill members, and covering panels 8 and 9 are secured to the opposite sides respectively to close the space in the frame below the window sill members.

In a practical application of the invention the inner sides of the posts 2 and 3 are provided with felt-lined guides 10 and 10 respectively for vertically guiding a window pane, the inner side of the top rail 4 having a similar guide 11 for the top of the window pane, the posts being provided also with guides 12 and 12 for a screen frame and the top rail having a guide 13 for the top of the screen frame. A pair of suitable stop blocks 14 and 14" are secured also to the posts at the lower ends of the vertical guides respectively, the topsof the blocks being suitably cushioned to noiselessly stop the window pane and screen frame.

A suitable plate glass window pane 15 is provided and arranged to operate in connection with vertical guides 10 and 10, and-its lower edge portion has a metallic control bracket 16 secured thereto which is provided with a pivot pin 17 to which a link rod 18 is connected and provided at' its lower end with a pivot pin 19 to ,which one end of a control lever 20 ispivoted, the opposite end of the lever being supported by a suitable pivot shaft or pin 21 suitably supported by the post 3 in proximity to the bottom rail 1, the shaft preferably being secured to the control lever and rotatively supported in a suitable casing 22 provided with a base 23 secured to the post 3 and preferably having a guide projection 24 thereon that extends upto the sto block 14', to facilitate accurate assembly the lever pivot relatively to the Window pane. Preferably a balancing spring 25 is arranged in the casing 22 and wrapped about the shaft 21, the inner end of the spring bein connected to the shaft and the outer end 0 the spring connected to the casing and under tension so asto force'the control lever upwardly against the gravity pressure of the window pane. When so preferred,'a long coil spring 26 is connected to .the lever 20 and to the rail as an auxiliary to the other spring so tliat'in emergency in case of fraction of one of the springs the window pane will be partially balanced; and

either one of the springs alone may be pro-' vided if so desired. For operating and con trolling the lever the cross-bar 7 is provided with a horizontal pivot device 27 on which an operating lever is supported between its ends, the lever having a lowerarm comprising a main portion 28 and a continurack-bar 34 on its end which has gear teeth 35 on its upper side. A crank shaft 36 is suitably supported rotatably in the inner panel 9 of the doorand has a pinion 37 fixed thereto which is in mesh with the gear teeth 35,

the crank shaft being partially supported by a suitable frame member 38 which is stationarily supported,.preferably' by the cross-bar 7 and the post 2.

A- rectangular screen frame 39 is guided for, vertical movement in the guides 12 and 12, being arranged to operate in proximity to the inner side of the window pane, and it has a suitable screen 40 secured therein. The screen and its frame,being of light weight may be easily lifted by hand to close the window opening against insects and dust, but preferably is provided with a fastener to hold it in closed position. Preferably a lifting plate 41 is connected to the upper portion of the screen frame by means of a ivot pin 42 permitting the'plate to be swung own behind the window sill member 6 and be unobstructive, the plate having a lateral finger 43 at its end and a notch 44 in its end to facilitate withdrawal of the plate from its rest position, and the plate also has a finger holdportion 45 on its front side to facilitate the lifting of the screen. A suitable lock device 46 is arranged in a recess in the top rail 4 and suitably secured in place, preferably by means of a shank 47 secured to the back of the guide 13-, the device 46 being adapted to be engaged by the lock finger 43 when the plate 41 is properly swung on its pivot.

The upper or actuating arm 33 of the operating lever may be variously adapted to be moved by hand without power gearing, the arm being of suitable length to afford ample lever power, preferably being provided with a shaft 48 rotatively connected to the arm and having a head portion 49 fixed thereto, the shaft extending through an arcuate slot 50 in the inner panel 9 of the door and having a knob 51 on its end. The head member has fingers 52 and 53 integral with opposite sides thereof, a latch rod 54 is arranged on the arm 33 in guides55 and 55' and has a latch tooth 56 on its lower end, the upper end of the latch rod having opposite arms 57 and 58 provided with inwardly extending lugs 59 and 60 in engagement with the fingers 52 and 53 respectively, whereby to withdraw the latch which is automatically projected by means of a coil spring 61 arranged between the head portion 49 and the rod 54. A quadrant 62 having teeth 63 is suitably supported to be engaged by the latch, preferably being integral with a standard 64 secured to the cross-bar 7.,

In practical use the window pane may be lowered in fair weather or it may be raised entirely or partially when desired and is held when adjusted so as to prevent shifting of position during movements of the automobile,

the holding of the window pane to adjusted position preferably being accomplished by means 'of the arm 33 of the operating lever and the gear teeth devices described. The weight of the window pane being balanced or approximately so, is easily moved upward or downward and requires only slight turning of the primaryactuating device, such as the crank shaft'36 or the shaft 48. When the knob 51 is grasped by hand it is first slightly turned either forward or reversely to Withdraw the latch 56 and immediately pushed so as to move the arm 33 in the required direction to shift the window pane, the lever arm being automatically locked upon release of the knob. The pinion 37 in connection with the rack-bar 34 holds the lever arm 33 when the crank shaft 36 is at rest. lVhen it is desired to screen the window when open the lock plate 41 is readily swung up from its rest position to an upper position and used as a lift handle to raise the screen nearly to closed pcigreaeae sition, permitting the screen frame to be further lifted by hand and the lock plate manipulated to bring the lug 43 into connection with the lock device 46 to securely lock the screen in closed position, Upon reverse manipulation the screen may be quickly lowered into its casing and out of sight. When driving with open windows, if a rain storm suddenly develops the windows may be quickly closed without requiring confusing movements or tedious turning of cranks, it being designed that the window pane be fullyshifted with a single rotation of the crank shaft 36.
